ABSTRACT

Background Galectin-3 (Gal-3) is a proinflammatory, profibrotic molecule implicated in the pathogenesis of heart failure. The role of Gal-3 in patients with chronic constrictive pericarditis (CCP) is not clear. Objective The aim of this study was to assess plasma Gal-3 in patients with CCP and correlate it with clinical, functional and histologic parameters. Methods We prospectively evaluated 25 symptomatic patients with CCP referred for pericardiectomy and 21 healthy controls. Patients underwent clinical assessment, Gal-3 and B-type natriuretic peptide (BNP) measurements, echocardiography, cardiac magnetic resonance imaging and cardiopulmonary exercise test (CPET) at baseline. Six months after pericardiectomy CPET was repeated. An alpha error < 5% was considered statistically significant, with a confidence interval of 95%. Results Twenty-five patients with a median age of 45 years were included. Etiology was mainly idiopathic (n = 19, 76%); and 14 (56%) patients had NYHA functional class III/IV. Median BNP and Gal-3 were 143 (89-209) pg/dL and 14.8 (9.7-17.2) ng/mL, respectively. Gal-3 levels were not significantly higher in CCP patients than in control (p = 0.22). There were no significant correlations of Gal-3 with BNP, echocardiographic and cardiac magnetic resonance measures and histological findings. After pericardiectomy, it was found a statistically significant correlation between Gal-3 and the CPTE measures test duration (r = -0.79; p < 0.001) and exercise time (r = -0.79; p < 0.001). Conclusions Patients with CCP had normal levels of Gal-3 as compared to the controls. Gal-3 did not correlate with morphological and functional measures before pericardiectomy. However, the associations between Gal-3 and exercise intolerance after pericardiectomy may suggest a role of Gal-3 in prognosis prediction after pericardiectomy.

ABSTRACT

FUNDAMENTO: A galectina-3 (Gal-3) é uma molécula pró-inflamatória e pró-fibrótica, envolvida na patogênese da insuficiência cardíaca. O papel da Gal-3 em pacientes com pericardite constritiva crônica (PCC) não está claro. OBJETIVO: O objetivo deste estudo foi avaliar os níveis de Gal-3 em pacientes com PCC e correlacioná-los com parâmetros clínicos, funcionais e histológicos. MÉTODOS: Nós avaliamos prospectivamente 25 pacientes sintomáticos com PCC agendados à pericardiectomia e 21 controles sadios. Os pacientes foram submetidos à avaliação clínica, medidas de Gal-3 e peptídeo natriurético do tipo B (BNP), ecocardiografia, ressonância magnética cardíaca e teste cardiopulmonar de exercício (TCPE) no período basal. Seis meses após a pericardiectomia, repetiu-se o TCPE. Um erro alfa < 5% foi considerado estatisticamente significativo, com um intervalo de confiança de 95%. RESULTADOS: Foram incluídos 25 pacientes com idade mediana de 45 anos. A etiologia foi principalmente idiopática (n = 19, 76%), e 14 (56%) apresentaram classe funcional New York Heart Association (NYHA) III/IV. Os valores medianos de BNP e Gal-3 foram 143 (89-209) pg/dL e 14,8 (9,7-17,2) ng/mL, respectivamente. Os níveis de Gal-3 não foram estatisticamente maiores nos pacientes com PCC que em controles (p = 0,22). Não foram encontradas correlações significativas da Gal-3 com BNP, medidas ecocardiográficas e de ressonância magnética cardíaca, e achados histológicos. Após a pericardiectomia, encontrou-se uma correlação estatisticamente significativa entre Gal-3 e medidas do TCPE ­ duração do teste (r = ­0,79; p < 0,001) e tempo de exercício (r = ­0,79; p < 0,001). CONCLUSÕES: Pacientes com PCC apresentaram níveis normais de Gal-3, quando comparados aos indivíduos controles. A Gal-3 não se correlacionou com medidas morfológicas e funcionais antes da pericardiectomia. No entanto, associações entre Gal-3 e intolerância ao exercício após pericardiectomia pode sugerir um papel da Gal-3 na predição de prognóstico após a pericardiectomia.

ABSTRACT

BACKGROUND: Heart failure is associated with exercise intolerance and sleep- disordered breathing; however, studies in patients with chronic constrictive pericarditis are scarce. The purpose of our study was to assess exercise capacity and sleep in patients with chronic constrictive pericarditis (CCP) undergoing a pericardiectomy. METHODS: We studied consecutive patients scheduled for pericardiectomy due to symptomatic CCP. Were performed quality of life (Minnesota Living with Heart Failure Questionnaire-MLHFQ) and sleep questionnaires (Epworth, Pittsburgh Sleep Quality Index-PSQI), serum B-type natriuretic peptide (BNP), serum C-reactive protein, transthoracic echocardiography, cardiopulmonary exercise test and overnight polysomnography immediately before and six months after pericardiectomy. RESULTS: Twenty-five patients (76% males, age: 45.5±13.8 years, body mass index: 24.9±3.7 kg/m2, left ventricular ejection fraction: 60±6%) with CCP (76% idiopathic, 12% tuberculosis) were studied. As compared to the preoperative period, pericardiectomy resulted in reduction in BNP (143 (83.5-209.5) vs 76 (40-117.5) pg/mL, p = 0.011), improvement in VO2 peak (18.7±5.6 vs. 25.2±6.3 mL/kg/min, p<0.001), quality of life (MLHFQ score 62 (43,5-77,5) vs. 18 (8,5-22), p<0,001) and sleep (PSQI score 7.8±4.1 vs. 4.7±3.7, p<0.001) and no significant change in sleep disordered breathing (apnea hypopnea index-AHI 15.6 (8.3-31.7) vs. 14.6 (5.75-29.9) events/h, p = 0.253). CONCLUSION: Patients with symptomatic CCP showed reduced exercise capacity and sleep-disordered breathing. After pericardiectomy, there was improvement in exercise capacity and neutral effect on sleep-disordered breathing.

ABSTRACT

Abstract Background: International studies have reported the value of the clinical profile and laboratory findings in the diagnosis of constrictive pericarditis. However, Brazilian population data are scarce. Objective: To assess the clinical characteristics, sensitivity of imaging tests and factors related to the death of patients with constrictive pericarditis undergoing pericardiectomy. Methods: Patients with constrictive pericarditis surgically confirmed were retrospectively assessed regarding their clinical and laboratory variables. Two methods were used: transthoracic echocardiography and cardiac magnetic resonance imaging. Mortality predictors were determined by use of univariate analysis with Cox proportional hazards model and hazard ratio. All tests were two-tailed, and an alpha error ≤ 5% was considered statically significant. Results: We studied 84 patients (mean age, 44 ± 17.9 years; 67% male). Signs and symptoms of predominantly right heart failure were present with jugular venous distention, edema and ascites in 89%, 89% and 62% of the cases, respectively. Idiopathic etiology was present in 69.1%, followed by tuberculosis (21%). Despite the advanced heart failure degree, low BNP levels (median, 157 pg/mL) were found. The diagnostic sensitivities for constriction of echocardiography and magnetic resonance imaging were 53.6% and 95.9%, respectively. There were 9 deaths (10.7%), and the risk factors were: anemia, BNP and C reactive protein levels, pulmonary hypertension >55 mm Hg, and atrial fibrillation. Conclusions: Magnetic resonance imaging had better diagnostic sensitivity. Clinical, laboratory and imaging markers were associated with death.


Resumo Fundamento: Estudos internacionais têm relatado o valor de perfil clínico e exames de imagem no diagnóstico e prognóstico da pericardite constritiva. Entretanto, dados da população brasileira são escassos. Objetivo: Avaliar as características clínicas, sensibilidade de exames de imagem e fatores relacionados ao óbito em uma série de casos de pericardite constritiva submetidos à pericardiectomia. Métodos: Pacientes com pericardite constritiva confirmada por cirurgia foram avaliados retrospectivamente quanto a variáveis clínicas e laboratoriais. Dois métodos diagnósticos foram utilizados: ecocardiograma transtorácico e ressonância cardíaca. Preditores de mortalidade foram determinados por análise univariada usando metodologia das proporções de Cox e hazard ratio. Todos os testes foram considerados bicaudais e um erro alfa ≤ 5% foi considerado como significante. Resultados: Foram estudados 84 pacientes com idade média de 44 ± 17,9 anos, sendo 67% do sexo masculino. Sinais e sintomas de insuficiência cardíaca (IC) predominantemente direita estiveram presentes com estase jugular, edema e ascite em 89%, 89% e 62% dos casos, respectivamente. Etiologia idiopática foi observada em 69% dos casos, seguida por tuberculose em 21%. Apesar do grau de IC, encontramos baixos níveis de BNP (mediana de 157 pg/mL). As sensibilidades diagnósticas para constrição do ecocardiograma e da ressonância foram 53,6% e 95,9%, respectivamente. Durante a evolução clínica, houve 9 óbitos (10,7%) e os fatores de risco foram: anemia, elevações de BNP, PCR, hipertensão pulmonar > 55 mmHg e fibrilação atrial. Conclusões: Pericardite constritiva manifesta-se com sinais e sintomas de IC biventricular com predomínio à direita e baixos níveis de BNP. A ressonância magnética apresenta melhor sensibilidade para diagnóstico. Marcadores clínicos, laboratoriais e de imagem estiveram associados ao óbito.

ABSTRACT

Acute pericarditis is a common disease caused by inflammation of the pericardium, usually benign and self-limited and can occur as an isolated or as a manifestation of a systemic disease entity. Represents 5% of all causes of chest pain in the emergency room. The main etiology are viral infections, although it can also be secondary to systemic diseases and infections. The main complication of acute pericarditis is pericardial effusion, triggering a cardiac tamponade. The first line of treatment is the use of anti-inflammatory and or acetylsalicylic acid. Most patients have a good initial response to an NSAID associated to colchicine and became asymptomatic within a few days. This review article seeks to contemplate the main clinical findings and armed investigation to optimize the diagnosis of this important disease, as well as addressing their therapeutic management.

Resumo A pericardite aguda é uma doença comum causada pela inflamação do pericárdio, geralmente benigna e autolimitada, podendo ocorrer como entidade isolada ou como manifestação de uma patologia sistêmica. Representa 5% de todas as causas de dor torácica na sala de emergência. A principal etiologia são as infecções virais, embora também possa ser secundária a afecções sistêmicas. A principal complicação da pericardite aguda é o derrame pericárdico, desencadeando um tamponamento. A primeira linha de tratamento é uso de anti-inflamatórios ou ácido acetilsalicílico. A maioria dos pacientes tem boa resposta inicial a um anti-inflamatório não esteroide (AINE) associado à colchicina e torna-se assintomática em poucos dias. Este artigo busca contemplar os principais achados clínicos e de propedêutica armada para otimizar o diagnóstico dessa patologia, bem como abordar o seu manejo terapêutico.

ABSTRACT

The association of anomalous right coronary artery originating from the pulmonary artery and constrictive pericarditis has never been showed in the literature. We present the first case of this unusual association in a patient with right heart failure. After diagnosis, the patient was referred to surgery and underwent phrenic-to-phrenic pericardiectomy; graft implant of right internal thoracic artery to right coronary artery; and ligation of the anomalous origin of the right coronary artery from the pulmonary artery. Such procedures solved the potential risk of sudden death related to anomalous right coronary artery originating from the pulmonary artery and alleviated the symptoms of heart failure caused by constrictive pericarditis.

ABSTRACT

A associação da artéria coronária direita anômala com origem na artéria pulmonar e pericardite constritiva ainda não foi descrita na literatura. Apresentamos aqui o primeiro caso dessa associação inusitada em um paciente com quadro de insuficiência cardíaca direita. Após o diagnóstico, o paciente foi encaminhado para tratamento cirúrgico, sendo submetido a pericardiectomia frênico a frênico, implante de enxerto da artéria mamária interna direita para a coronária direita e ligadura da origem anômala da coronária direita da artéria pulmonar. Tais procedimentos resolveram o potencial risco de morte súbita pela anomalia coronária e aliviaram os sintomas de insuficiência cardíaca causados pela pericardite constritiva.
